Selon un <a href=\"https:\/\/www.strabag.ch\/aktuelles\/2024-10\/hirschenbruecke-lachen-nach-altendorf\" target=\"_blank\" rel=\"noopener\">communiqu\u00e9<\/a>, le pont pour pi\u00e9tons, v\u00e9los et v\u00e9hicules l\u00e9gers relie les deux localit\u00e9s de Lachen et d&rsquo;Altendorf dans le canton de Schwyz et fait passer le trafic au-dessus des voies de train de la ligne Zurich-Coire. Actuellement, tous les usagers de la route utilisent le m\u00eame pont. Afin d&rsquo;am\u00e9liorer la s\u00e9curit\u00e9 de la mobilit\u00e9 douce, le canton de Schwyz a pr\u00e9vu un pont suppl\u00e9mentaire qui sera construit \u00e0 c\u00f4t\u00e9 du pont existant.<\/p>\n<p class=\"bodytext\">D&rsquo;ici fin 2024, les travaux de construction de la nouvelle passerelle seront termin\u00e9s, pr\u00e9cise le communiqu\u00e9. En 2025 suivront les travaux pour les ouvrages de raccordement ainsi que l&rsquo;am\u00e9nagement de la route. Il faudra probablement attendre fin 2025 pour que le nouveau pont soit ouvert \u00e0 la circulation douce.<\/p>\n<p class=\"bodytext\">Selon Strabag, le nouveau pont est tr\u00e8s mince et a \u00e9t\u00e9 con\u00e7u comme un arc \u00e0 trois articulations. Il reprend ainsi le langage formel de l&rsquo;ancien pont Hirschen, con\u00e7u en 1940 par l&rsquo;ing\u00e9nieur civil Robert Maillart.<\/p>\n<p class=\"bodytext\">Selon Strabag, la construction a \u00e9t\u00e9 pr\u00e9c\u00e9d\u00e9e d&rsquo;importants travaux pr\u00e9paratoires tels que la s\u00e9curisation des fouilles et l&rsquo;ancrage des fondations au moyen de micropieux. L&rsquo;excavation du pont pr\u00e9fabriqu\u00e9 a \u00e9t\u00e9 r\u00e9alis\u00e9e de nuit en seulement 3 heures et 15 minutes.  En ao\u00fbt, le g\u00e9nie civil a soulev\u00e9 les deux \u00e9l\u00e9ments d&rsquo;arche pr\u00e9fabriqu\u00e9s de 27,5 tonnes jusqu&rsquo;\u00e0 leur destination finale. Les travaux ont n\u00e9cessit\u00e9 la fermeture des voies des CFF, de la ligne de transmission, ainsi que de la route cantonale et du chemin de fer. En septembre, les deux \u00e9l\u00e9ments de bordure ont \u00e9galement \u00e9t\u00e9 install\u00e9s de nuit.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Strabag compl\u00e8te le pont Hirschen, class\u00e9 monument historique, qui relie Lachen \u00e0 Altendorf par un nouveau pont destin\u00e9 \u00e0 la mobilit\u00e9 douce.
